Cannot get fresh evaluation installation to run Edited

I have just installed a freah Jira Servicedesk on a fresh CentOS 7.3.1611 and cannot get it to run in another machine's browser (CentOS is Core). It seems to be able to reach tomcat but waits until it times out.

wget on localhost gets the index.html, though.

Everything looks fine in catalina.out, I guess, and in atlassian-jira-gc-XX.log (except a bunch of [GC (Allocation Failure)].

I am really new to this (hence the evaluation) and I'm at my wits' end.
